Bioceramics in Joint Arthroplasty

Ceramic acetabular cups have been used successfully for more than thirty years in total hip arthroplasty. Pioneering one piece designs are no longer used as a result of mechanical loosening complications related to their design. These early concepts were replaced in the late 80's with modular ceramic inserts used in conjunction with proven non-cemented hemispherical shells and have addressed well these early design related problems.Throughout this evolution, the performance and reliability of the ceramic components has been excellent. As a result of this and in answer to the challenge created by wear debris generated osteolysis, a renewed interest has surfaced in the ceramic on ceramic articulation.This renaissance has created a new alternative for the young and active patients in search of a more durable and longer term option Total Hip Replacement.The objective of the 7th BIOLOX Symposium has been to assemble experts and have them present the current state-of-the-art in the alternative bearing area along with their clinical experience with current generation of ceramic inserts.In addition a special chapter has been included which reviews the status and the options of ceramics for total knee replacement.
